Edge processing of sensor data using a neural network to reduce data traffic on a communication network

ABSTRACT

Methods, systems, and apparatuses related to edge processing of sensor data using a neural network to reduce network traffic to and/or from a server. In one approach, a cloud server processes sensor data from a vehicle using an artificial neural network (ANN). The ANN has several layers. Based on analyzing at least one characteristic of the sensor data received from the vehicle and/or a context associated with processing the sensor data, the cloud server determines to send one or more of the layers of the ANN for edge processing on the vehicle itself. In other cases, the cloud server decides to send the one or more layers to an edge server device located on a communication path between the vehicle and the cloud server. The edge processing reduces network data traffic.

FIELD OF THE TECHNOLOGY

At least some embodiments disclosed herein relate to neural network processing devices in general, and more particularly, but not limited to edge processing of sensor data using a neural network to reduce data traffic.

BACKGROUND

Recent developments in the technological area of autonomous driving allow a computing system to operate, at least under some conditions, control elements of a motor vehicle without the assistance from a human operator of the vehicle.

For example, sensors (e.g., cameras and radars) can be installed on a motor vehicle to detect the conditions of the surroundings of the vehicle traveling on a roadway. A computing system installed on the vehicle analyzes the sensor inputs to identify the conditions and generate control signals or commands for the autonomous adjustments of the direction and/or speed of the vehicle, with or without any input from a human operator of the vehicle.

In some arrangements, when a computing system recognizes a situation where the computing system may not be able to continue operating the vehicle in a safe manner, the computing system alerts the human operator of the vehicle and requests the human operator to take over the control of the vehicle and drive manually, instead of allowing the computing system to drive the vehicle autonomously.

Autonomous driving and/or an advanced driver assistance system (ADAS) can use an artificial neural network (ANN) for the identification of events and/or objects that are captured in sensor inputs. Examples of sensor inputs include images from digital cameras, lidars, radars, ultrasound sonars, etc.

In general, an artificial neural network (ANN) uses a network of neurons to process inputs to the network and to generate outputs from the network. For example, each neuron in the network receives a set of inputs. Some of the inputs to a neuron may be the outputs of certain neurons in the network; and some of the inputs to a neuron may be the inputs provided to the neural network. The input/output relations among the neurons in the network represent the neuron connectivity in the network.

For example, each neuron can have a bias, an activation function, and a set of synaptic weights for its inputs respectively. The activation function may be in the form of a step function, a linear function, a log-sigmoid function, etc. Different neurons in the network may have different activation functions. The relations between the input(s) and the output(s) of an ANN in general are defined by an ANN model that includes the data representing the connectivity of the neurons in the network, as well as the bias, activation function, and synaptic weights of each neuron.

For example, the inputs to an ANN network may be generated based on camera inputs; and the outputs from the ANN network may be the identification of an item, such as an event or an object.

DETAILED DESCRIPTION

The following disclosure describes various embodiments for edge processing of sensor data (e.g., processing at a vehicle or edge server) using a portion of a neural network to reduce data traffic to a remote computing device (e.g., cloud server). At least some embodiments herein relate to processing of sensor data using a computing device (e.g., a neural network processor) located in a vehicle. The processing is performed using a portion of an artificial neural network (ANN) received from a remote computing device that performs further processing using other portions of the ANN. In one example, the vehicle is an autonomous vehicle (e.g., car, boat, plane, or drone).

In prior approaches, mobile devices (e.g., an autonomous vehicle) can store and/or generate sensor data that needs to be processed in a cloud or other server (e.g., that is remotely located from the vehicle). For example, autonomous vehicles have ANNs configured to recognize and/or classify objects captured in camera images. Such images can be uploaded to the cloud or other server for processing, training, etc. The processing in the cloud or server is often performed via multiple layers of artificial neurons. After an image is processed by one or more layers, the output of the layers can be much smaller than the image itself.

However, sending image data for processing by the layers of the ANN at the cloud or server requires sending large data files or streams of image data (e.g., image streams from a camera of a vehicle). For example, this increases data traffic on the network (e.g., cellular or other wireless network) between a vehicle that collects the data and a remote cloud server. This significantly degrades performance of the network by requiring significant bandwidth to transfer the image or other sensor data. This also can cause a mobile device to consume excessive battery power, which may be limited for certain smaller mobile devices.

Various embodiments of the present disclosure provide a technological solution to one or more of the above technical problems. In one embodiment, a cloud server processes sensor data from a vehicle using an ANN. The ANN has several layers. In some cases, based on analyzing the nature of the sensor data (e.g., type or characteristic of data) received from the vehicle and/or other factors associated with a context associated with processing the sensor data (e.g., bandwidth consumption due to data traffic to or from the cloud server, and/or the environment in which a vehicle is operating such as daylight, night, and/or fog or rain), the cloud server decides to send one or more of the layers of the ANN for edge processing at the vehicle itself. In other cases, the cloud server decides to send the one or more layers to an edge server device located between the vehicle and the cloud server. By pushing processing for the one or more layers closer to the vehicle (or other source of data to be processed by an ANN), data traffic over one or more networks of a networked system can be decreased.

In one embodiment, an ANN includes a network of neurons stored on a computing device in memory. One layer of neurons generates outputs as inputs for the next layer of neurons. Each neuron takes one or more inputs to generate an output. In one example, one layer of neurons may be considered as one ANN and another layer of neurons as another ANN. Then, the connected layers are one combined ANN. The computation of a layer of neurons can be formulated to include an input vector multiplying a matrix for generating an output vector. In some cases, this matrix operation can be broken down into smaller matrix operations based on a hardware acceleration capability of one or more ANN accelerators.

In one embodiment, in view of the above, a computing device is configured to intelligently partition the computation of an ANN having multiple layers across multiple devices (e.g., cloud, edge server, vehicle, mobile device, etc.). For example, the vehicle has the sensors to generate the first input vector. The first input vector is to be multiplied by the matrix of a first layer of neurons to generate a first output vector for a second layer of neurons. Initially, all layers are in the cloud/server. If the cloud/server determines that it is advantageous for an edge server to process the first layer (instead of the cloud/server), the model of the first layer is pushed to the edge server such that the cloud/server gets the first output vector from the edge server, instead of the first input vector from the vehicle or edge server.

In one embodiment, the cloud/server monitors its ANN to determine which of one or more layers can be pushed to one or more edge servers configured on the communication paths from mobile devices to the cloud/server. When the processing by the pushed layers of the ANN is sufficient, the original images do not have to be uploaded to the cloud/server. Otherwise, the original images can be further uploaded from the edge servers to the cloud/server for further processing, as may be needed in certain cases.

In one embodiment, the ANN at the cloud/server can estimate a probability of an edge server uploading images after processing using the one or more layers of ANNs specified by the cloud/server if pushed to a vehicle or edge server for processing closer in a network to the source of the data for the images. In one embodiment, the cloud/server pushes processing to edge servers based on balancing the costs and benefits of processing at the edge servers over the required data traffic of pushing the layers to the edge servers, and the data traffic of uploading both the processing results of the edge servers and the original images when the processing results are insufficient.

In one embodiment, one or more portions of an ANN are selected by a server and pushed to a vehicle. In one example, each of the portions is a layer of the ANN. In one example, each of the portions is a portion of data for a neuron model of the ANN.

In one embodiment, a networked system (e.g., a network that provides a wireless and/or wired communication path between a vehicle and a cellular base station and/or server) includes at least one processing device (e.g. a CPU of a cloud server), and memory containing instructions configured to instruct the at least one processing device to perform a method. The method includes: receiving data over a network from a computing device (e.g., a controller of a memory device located in a vehicle), wherein the received data is processed using an artificial neural network (ANN), the ANN comprises a neuron model used for processing the data, and the computing device provides the data from processing sensor data obtained from at least one sensing device of a vehicle (e.g., a camera of the vehicle); sending, to the computing device, a first portion of the neuron model, wherein the first portion is selected based on predicted data traffic associated with processing the sensor data, the predicted data traffic including at least one of data traffic to the computing device, or data traffic from the computing device; receiving, from the computing device, an intermediate result, wherein the computing device provides the intermediate result based on processing the sensor data using the first portion (e.g., output from processing sensor data using a first layer of the ANN); and providing, by processing the intermediate result using a second portion of the neuron model, an output (e.g., the intermediate result is input to a second layer of the ANN).

In one example, the output is used to control a system of a vehicle. In one example, a cloud server sends the output to the vehicle to cause a control action on the vehicle. In one example, the controlled system can be an engine, steering, braking, or other component of a vehicle that can be electronically controlled.

In one embodiment, a set of sensors is configured on a vehicle, and an edge server may be on the vehicle or in a base station (e.g., 5G base station or connected to the base station via a local area network), and the edge server communicates with a cloud server. Sensor data goes to the edge server and then to the cloud server. The edge server and the cloud server are separated by a network, and work together to process the sensor data using an ANN. The output from the ANN at the cloud server may or may not go back to the vehicle that provides the input sensor data.

In one example, a layer is a set of artificial neurons, and an intermediate result is the output of the artificial neurons in the layer downloaded to the edge server. An artificial neuron is a set of data that specifies the behavior of the neuron and/or its state. In one example, a layer of the ANN is identified that can be pushed to the edge server (e.g., finding an improved or optimal way to cut the ANN into two portions such that the portion that is the first layer can be pushed to the edge server for an improved or optimal result).

FIG. 1 illustrates a data processing system that uses edge processing of data (e.g., sensor or other data) to reduce data traffic on a network (e.g., data traffic between a mobile device such as a vehicle and the cloud using a wireless network, where the data traffic is associated with processing of sensor data collected by the mobile device) according to one embodiment. A vehicle 102 contains one or more sensing device(s) 104. A computing device 110 within the vehicle 102 processes sensor data 106 from the sensing device 104 and outputs an intermediate result 130. The intermediate result 130 is sent through a network 136 to a computing device 138. The computing device 138 generally processes the intermediate result 130 using an artificial neural network (ANN) 150 to produce an output 162. The output 162 may be used to control an action 166 of the vehicle 102. To reduce data traffic 134, the computing device 138 may partition the ANN 150 into multiple portions (e.g., portion 154, portion 156, portion 158, etc.) and send portions of the ANN 150 to other devices (e.g., computing device 110) to process sensor data 106. In one example, each portion is part of a neuron model of ANN 150.

The vehicle 102 may be, for example, an autonomous vehicle. The sensing device 104 may be, for example, an image sensor, LIDAR, RADAR, GPS, or other type of sensor. The sensing device 104 outputs collected sensor data 106 (e.g., images, GPS location, etc.) to the computing device 110.

The computing device 110 may be, for example, a computer, embedded computer, controller in a vehicle, server, laptop, tablet or other electronic device controlled by a processing device. In some embodiments, the computing device 110 may be described as an edge processing device.

In one embodiment, the computing device 110 contains a processing device 116 and memory 118. The processing device 116 may be, for example, a microprocessor, graphics processor, embedded processor, embedded controller, central processing unit (CPU), system on a chip (SOC), application specific integrated circuit (ASIC), field programmable gate array (FPGA), or other processing device. The processing device 116 may be composed of a single processor with a single processing core, a single processor with multiple processing cores, or multiple processors. The processing device 116 and memory 118 may be configured on a printed circuit board. In some instances, the processing device 116 and the memory 118 are packaged together in a System on Chip (SoC).

The memory 118 can include volatile memory (e.g., DRAM and/or SRAM) and/or non-volatile memory. The memory 118 may be separate from the processing device 116 (e.g., DIMM modules, SIMM modules, NVMe modules, etc.) or may be embedded within the processing device 116 (e.g., High Bandwidth Memory (HBM)).

Examples of non-volatile memory include flash memory, memory units formed based on negative-and (NAND) logic gates, negative-or (NOR) logic gates, Phase-Change Memory (PCM), magnetic memory (MRAM), resistive random-access memory (RRAM), cross point memory, and other memory devices. A cross point memory device can use transistor-less memory elements, each of which has a memory cell and a selector that are stacked together as a column. Memory element columns are connected via two lays of wires running in perpendicular directions, where wires of one lay run in one direction in the layer located above the memory element columns, and wires of the other lay are in another direction and in the layer located below the memory element columns. Each memory element can be individually selected at a cross point of one wire on each of the two layers. Cross point memory devices are fast and non-volatile and can be used as a unified memory pool for processing and storage. Further examples of non-volatile memory include Read-Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Programmable Read-Only Memory (EPROM) and Electronically Erasable Programmable Read-Only Memory (EEPROM), etc.

The memory 118 contains instructions 120 instructing the processing device 116 to perform tasks such as, for example, receive a portion 154 of the ANN 150 from the computing device 138, process sensor data 106 using the ANN 122, send an intermediate result 130 to the computing device 138 after processing sensor data 106, etc.

The processing device 116 sends an intermediate result 130 through a network 136 to the computing device 138. The network 136 may include wireless networks or combinations of wireless and wired networks. The network 136 may also include networking services such as, for example, cellular phone, satellite, or internet services and networking equipment such as, satellites, cellular phone towers, cellular phone base stations, network switches, network routers, etc. The volume of data (e.g., Megabytes/second or Gigabytes/second) transmitted between the computing device 138 and the computing device 110 is represented in FIG. 1 as data traffic 134. Data traffic 134 may include, for example, an intermediate result 130 sent to the computing device 138, sensor data 106 sent to the computing device 138 for further processing, a portion 154 of the ANN 150 sent to the computing device 110, a portion 158 of the ANN 150 sent to the sensing device 104, etc.

The computing device 138 receives input data 140 (e.g., intermediate result 130) from the network 136. The computing device 138 may be, for example, a computer, embedded computer, server, laptop, tablet or other electronic device controlled by a processing device.

In one embodiment, the computing device 138 contains a processing device 144 and memory 146. The processing device 144 may be, for example, a microprocessor, graphics processor, embedded processor, embedded controller, central processing unit (CPU), system on a chip (SOC), application specific integrated circuit (ASIC), field programmable gate array (FPGA), or other processing device. The processing device 144 and memory 146 may be configured on a printed circuit board. In some instances, the processing device 144 and the memory 146 are packaged together in a System on Chip (SoC).

The memory 146 can include volatile memory (e.g., DRAM and/or SRAM) and/or non-volatile memory (e.g., NAND flash, NOR flash, PCM, MRAM, RRAM, cross point memory, ROM, PROM, EPROM, EEPROM, etc.). The memory 146 may be separate from the processing device 144 (e.g., DIMM modules, SIMM modules, NVMe modules, etc.) or may be embedded within the processing device 144 (e.g., HBM memory).

The memory 146 contains instructions 148 instructing the processing device 144 to perform tasks such as, for example, receive a request from the computing device 110 for a portion 154 of the ANN 150, send a portion 154 of the ANN 150 to the computing device 110, process input data 140 (e.g., intermediate result 130) using at least a portion 156 of the ANN 150, provide output 162 based on processing the intermediate result 130 from the computing device 110, etc.

The processing device 144 contains the ANN 150 (e.g., stored in memory). The ANN 150 uses a network of neurons to process inputs to the network and to generate outputs from the network.

For example, each neuron in the network receives a set of inputs. Some of the inputs to a neuron may be the external inputs provided into the neural network and some of the inputs to a neuron may be the outputs of certain neurons in the network. The input/output relations among the neurons in the network represent the neuron connectivity in the network.

For example, each neuron can have a bias, an activation function, and a set of synaptic weights for its inputs respectively. The activation function may be in the form of a step function, a linear function, a log-sigmoid function, etc. Different neurons in the network may have different activation functions.

For example, each neuron can generate a weighted sum of its inputs and its bias and then produce an output that is the function of the weighted sum, computed using the activation function of the neuron. Input to an ANN can be described as an input vector and the output can be described as an output vector.

The relations between the input(s) and the output(s) of an ANN in general are defined by a neuron model that includes the data representing the connectivity of the neurons in the ANN, as well as the bias, activation function, and synaptic weights of each neuron. Using a given neuron model 152, a computing device 138 computes the output 162 of the ANN 150 from a given set of input data 140 to the ANN 150.

For example, input data 140 to the ANN 150 may be generated based on camera output from the sensing device 104. The output 162 from the ANN 150 may be the identification of an item, such as an object or an event.

In one embodiment, the ANN 150 is a spiking neural network (SNN). An SNN is a type of ANN that closely mimics natural neural networks. An SNN neuron produces a spike as output when the activation level of the neuron is sufficiently high. The activation level of an SNN neuron mimics the membrane potential of a natural neuron. The outputs/spikes of the SNN neurons can change the activation levels of other neurons that receive the outputs. The current activation level of an SNN neuron as a function of time is typically modeled using a differential equation and considered the state of the SNN neuron. Incoming spikes from other neurons can push the activation level of the neuron higher to reach a threshold for spiking. Once the neuron spikes, its activation level is reset. Before spiking, the activation level of the SNN neuron can decay over time, as controlled by the differential equation. The element of time in the behavior of SNN neurons makes an SNN suitable for processing spatiotemporal data. The connectivity of an SNN is often sparse, which is advantageous in reducing computational workload.

In general, an ANN may be trained using a supervised method where the parameters in the ANN are adjusted to minimize or reduce the error between known outputs resulted from respective inputs and computed outputs generated from applying the inputs to the ANN. Examples of supervised learning/training methods include reinforcement learning, and learning with error correction.

Alternatively, or in combination, an ANN may be trained using an unsupervised method where the exact outputs resulting from a given set of inputs are not known before the completion of the training. The ANN can be trained to classify an item into a plurality of categories, or data points into clusters. Multiple training algorithms can be employed for a sophisticated machine learning/training paradigm.

The computing device 110 takes input data 112 (e.g., sensor data 106) and generates an intermediate result 130. In one embodiment, the computing device 110 passes input data 112 out as an intermediate result 130 without processing the input data 112 with an ANN. The computing device 138 takes the intermediate result 130 as input data 140. The ANN 150 uses the input data 140 as input to the neuron model 152 and calculates an output 162.

The computing device 138 may determine that data traffic 134 between the computing device 110 and the computing device 138 may be reduced by processing a portion of the sensor data 106 within the computing device 110. The computing device 138 may select a set of neurons (e.g., a portion 154 of the ANN 150) and send the set of neurons to the computing device 110 to form an ANN 122 within the computing device 110.

In one example, ANN 122 is a subset of ANN 150. In one example, ANN 122 includes neuron model data that is not present in ANN 150. In one example, ANN 122 is maintained by computing device 138 to include some or all portions of ANN 150 (e.g., the included portions may be predetermined or determined in real-time based on a context of vehicle 102).

The computing device 138 may select the set of neurons for sending to computing device 110 based on factors such as, for example, comparing the predicted data size 114 of input data 112 into the computing device 110 to the predicted data size 132 of the intermediate result 130 output from the computing device 110; or comparing the predicted data size 114 of the input data 112 to be processed using the portion 154 of the ANN 150 to the data size 160 of the portion 154 of the ANN 150; or predicting whether sensor data 106 will need to be uploaded to the computing device 138 for further processing after the intermediate result 130 is provided.

For example, the computing device 110 may receive sensor data 106 (e.g., image data from an image sensor). The computing device 138 may predict the data size 114 (e.g., a 10 MB per second input vector) of the sensor data 106 input to the computing device 110. The computing device 138 may predict that the data size 132 of the intermediate result 130 output from computing device 110 will be smaller (e.g., 1 MB per second output vector) if some of the processing performed by the ANN 150 (e.g., detecting objects in an image) is performed by the computing device 110. The computing device 138 may select a portion 154 of the neuron model 152 (e.g., neurons associated with detecting objects in images) and send the portion 154 of the neuron model 152 to the computing device 110 to be implemented as a neuron model 124 within an ANN 122. The ANN 122 takes sensor data 106 as an input vector, processes the data, and outputs an intermediate result 130 as an output vector.

In one example, sensor data 106 from the sensing device 104 (e.g., image data from an image sensor) may need to be sent to the computing device 138 for further processing after the intermediate result 130 has been provided. This may be due, for example, to glare causing an inconclusive intermediate result 130. The computing device 138 may include predicting whether the sensor data 106 will need to be uploaded to the computing device 138 for further processing as part of determining whether to perform processing for a portion 154 of the ANN 150 on the computing device 110.

In one example, the computing device 138 may predict a certain data size 108 from the sensing device 104. The computing device 138 may determine that a portion 154 of the ANN 150 used for processing sensor data 106 is smaller than the predicted data size 108 of the sensor data 106 from the sensing device 104. For example, the computing device 138 may predict a data size 108 of 1 TB from the sensing device 104. The computing device 138 may determine, for example, that a portion 154 of the ANN 150 has a data size 160 of 50 MB. The computing device 138 may select a portion 154 of the ANN 150 to send to the computing device 110 based on the data size 160 of the portion 154 of the ANN 150 being less than the predicted data size 108 of the sensor data 106 from the sensing device 104.

In one embodiment, the processing device 116 predicts data traffic 134 between the computing device 110 and the computing device 138 generated by processing the sensor data 106. Based on the predicted data traffic 134, the processing device 116 may request a portion 154 of the ANN 150 from the computing device 138. The computing device 138 sends a portion 154 of the ANN 150 to the processing device 116. The processing device 116 uses the portion 154 of the neuron model 152 from the computing device 138 to create a neuron model 124 within an ANN 122. The processing device 116 uses the ANN 122 to process sensor data 106 and output an intermediate result 130.

For example, sensor data 106 may be image data from a camera. The processor 116 may predict that sending the image data as an intermediate result 130 to the computing device 138 will result in a large amount of data traffic 134 (e.g., data size 132 of 15 MB per second). The processing device 116 may request a portion 154 of the ANN 150 and implement the received portion 154 in an ANN 122. The processor 116 processes the image data using the ANN 122 (e.g., identifying or classifying objects or events). After processing the image data, the data size 132 of the intermediate result 130 may be smaller (e.g., 2 MB per second) resulting in less data traffic 134.

The computing device 138 takes input data 140 (e.g., an intermediate result 130) and processes the data using a portion 156 of the ANN 150 to generate an output 162. The output 162 may be sent back to the vehicle 102. The vehicle 102 may use the output 162 to control an action 166 of the vehicle 102. For example, an intermediate result 130 may identify an object or an event (e.g., a pedestrian entering the path of the vehicle). The output 162 may instruct an action 166 for the vehicle 102 (e.g., stop or change lanes). The vehicle 102 may control an action 166 of the vehicle 102 (e.g., apply the brakes or steer the vehicle) based on the output 162.

In various embodiments, edge processing of sensor data as described above can be implemented in a networked system that permits communication between a vehicle and a cloud server (or other computing device). The networked system includes at least one vehicle and at least one computing device (e.g., vehicle 102, and computing devices 110, 138). The networked system is configured to implement edge processing using a portion of an ANN selected and sent from a computing device to reduce data traffic in the networked system.

The networked system is networked via one or more communications networks. The communication networks (e.g., network 136) can include at least a local device network such as Bluetooth or the like, a wide area network (WAN), a local area network (LAN), the Intranet, a mobile wireless network such as 4G or 5G, an extranet, the Internet, and/or any combination thereof. Nodes of the networked system (e.g., vehicles and/or other mobile/computing devices) can each be a part of a peer-to-peer network, a client-server network, a cloud computing environment, or the like. Also, any of apparatuses, computing devices, vehicles, sensors or cameras, and/or user interfaces in the networked system can include a computing system of some sort. A computing system can include a network interface to other devices in a LAN, an intranet, an extranet, and/or the Internet. The computing system can also operate in the capacity of a server or a client machine in a client-server network environment, as a peer machine in a peer-to-peer (or distributed) network environment, or as a server or a client machine in a cloud computing infrastructure or environment.

FIG. 2 illustrates an embodiment in which computing device 138 determines to perform processing for portion 158 of the ANN 150 on the vehicle 102 (e.g., in the sensing device 204). The computing device 138 sends portion 158 of the ANN 150 to the sensing device 204. The sensing device 204 uses the portion 158 of the neuron model 152 from the computing device 138 to create a neuron model 270 within an ANN 268. The sensing device 204 uses the ANN 268 to process data collected from the sensing device 204 and outputs the processed data as sensor data 206. The computing device 110 takes the sensor data 206 as input data 112 and further processes the data using the ANN 122 to output an intermediate result 130. In this configuration, the sensing device 204 may be described as an edge processing device.

For example, the sensing device 204 may be an image sensor. The computing device 138 may determine it is advantageous to process data from the image sensor within the image sensor itself (e.g., by performing object identification). The computing device 138 sends a portion 158 of the ANN 150 to the sensing device 204. The sensing device 204 uses the portion 158 of the neuron model 152 to create a neuron model 270 within ANN 268. The sensing device 204 uses the ANN 268 to process data collected from the image sensor and outputs sensor data 206 (e.g., an object identified as a pedestrian).

The processing device 116 takes input data 112 (e.g., sensor data 206), further processes the input data 112 using the ANN 122, and outputs an intermediate result 130. For example, the intermediate result 130 may be an event detection (e.g., that the trajectory of the pedestrian identified in the sensor data 206 will intersect the trajectory of the vehicle 102). Performing processing of portion 158 of the ANN 150 within the sensing device 204 may reduce the data size 208 of the sensor data 206 from the sensing device 204 and reduce data traffic 134 to the computing device 138, since the sensing device 204 would not need to send all the image data out for processing.

The description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding. However, in certain instances, well-known or conventional details are not described in order to avoid obscuring the description. References to one or an embodiment in the present disclosure are not necessarily references to the same embodiment; and, such references mean at least one.

Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Moreover, various features are described which may be exhibited by some embodiments and not by others. Similarly, various requirements are described which may be requirements for some embodiments but not other embodiments.

In this description, various functions and/or operations may be described as being performed by or caused by software code to simplify description. However, those skilled in the art will recognize what is meant by such expressions is that the functions and/or operations result from execution of the code by one or more processing devices, such as a microprocessor, Application-Specific Integrated Circuit (ASIC), graphics processor, and/or a Field-Programmable Gate Array (FPGA). Alternatively, or in combination, the functions and operations can be implemented using special purpose circuitry (e.g., logic circuitry), with or without software instructions. Embodiments can be implemented using hardwired circuitry without software instructions, or in combination with software instructions. Thus, the techniques are not limited to any specific combination of hardware circuitry and software, nor to any particular source for the instructions executed by a computing device.

While some embodiments can be implemented in fully functioning computers and computer systems, various embodiments are capable of being distributed as a computing product in a variety of forms and are capable of being applied regardless of the particular type of computer-readable medium used to actually effect the distribution.

At least some aspects disclosed can be embodied, at least in part, in software. That is, the techniques may be carried out in a computing device or other system in response to its processing device, such as a microprocessor, executing sequences of instructions contained in a memory, such as ROM, volatile RAM, non-volatile memory, cache or a remote storage device.

Routines executed to implement the embodiments may be implemented as part of an operating system, middleware, service delivery platform, SDK (Software Development Kit) component, web services, or other specific application, component, program, object, module or sequence of instructions (sometimes referred to as computer programs).

The computer programs typically comprise one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processors in a computer, cause the computer to perform operations necessary to execute elements involving the various aspects.

A computer-readable medium can be used to store software and data which when executed by a computing device causes the device to perform various methods. The executable software and data may be stored in various places including, for example, ROM, volatile RAM, non-volatile memory and/or cache.

Additional examples of computing devices include devices that are part of what is called “the internet of things” (IOT). Such “things” may have occasional interactions with their owners or administrators, who may monitor the things or modify settings on these things. In some cases, such owners or administrators play the role of users with respect to the “thing” devices. In some examples, the primary mobile device (e.g., an Apple iPhone) of a user may be an administrator server with respect to a paired “thing” device that is worn by the user (e.g., an Apple watch).

In some embodiments, the computing device can be a computer or host system, which is implemented, for example, as a desktop computer, laptop computer, network server, mobile device, or other computing device that includes a memory and a processing device. The host system can include or be coupled to a memory sub-system so that the host system can read data from or write data to the memory sub-system.
